Miltonidium orchid plant named ‘CAMBLOQA’

ABSTRACT

A new and distinct variety of x Miltonidium plant named ‘CAMBLOQA’, particularly characterized by having dark red flowers with a large dark red-purple lip, 1-4 peduncles that are medium long and sturdy, leaves that are lanceolate and elongated to very elongated, and is propagated by meristem tissue culture is disclosed.

Genus and species:

Nothogenus: x Miltonidium.

Variety denomination: ‘CAMBLOQA’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of x Miltonidium plant, botanically known as x Miltonidium of the Orchidaceae family, and hereinafter referred to by the cultivar name ‘CAMBLOQA’.

Miltonia, Oncidium and Brassia and some other genera are a complex group of orchid species that are easily hybridized. The boundaries between the genera have been under discussion for the last several decades. According to the most recent classification by Pridgeon, Cribb, Chase and Rasmussen (Genera Orchidacearum), the plant herein described is most likely a complex hybrid between Miltonia and Oncidium species, hence called x Miltonidium.

All x Miltonidium plants exhibit a sympodial growth habit. The species typically have 4 to 6 leaves per mature pseudobulb: most of the time one lanceolate leaf with an acute apex grown on the apex of the pseudobulb and four leaves grown from the axis at the base (sympodial growth), with two leaves on each side. The peduncles vary in size from 20-70 cm.

x Miltonidium orchids are used as flowering potted-plants for home or interiorscape. x Miltonidium produces upright or pendent lateral racemes or panicles, often with many showy flowers which open in succession beginning with the lowermost. The flowers possess three sepals and two petals, the lateral ones being alike and having a peculiar labellum. Flower colors include various shades of pink, white, yellow, and red-brown.

x Miltonidium orchids are typically propagated from tissue culture. Asexual propagation of x Miltonidium is often done from off-shoots which arise from the lower bracts of the inflorescence. The resulting plants are detached from the mother plants and may be planted in a suitable substrate.

The new x Miltonidium ‘CAMBLOQA’ is particularly characterized by its attractive and unique dark red flowers with a large dark red-purple lip, economical propagation by tissue culture, early flowering, and a plant dimension suitable for packaging and shipping to the market.

‘CAMBLOQA’ is a product of a planned breeding program conducted by the inventor in Bleiswijk, The Netherlands.

The new x Miltonidium ‘CAMBLOQA’ originated from a cross made by the inventor in January 2005 in Bleiswijk, The Netherlands. The female parent is an orange x Miltonidium pot plant named ‘60000-0149’ (unpatented) and the male parent is a greyed-purple Oncidium pot plant named ‘60000-0165’ (unpatented). A single plant was selected by the inventor from within the progeny of the stated cross-pollination in a controlled greenhouse in Bleiswijk, The Netherlands in July 2008.

Asexual reproduction of ‘CAMBLOQA’ by meristem tissue culture since 2011 in Bleiswijk, The Netherlands has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations.

Plant Breeder's Rights for this variety have been applied for in Europe on Nov. 25, 2016. ‘CAMBLOQA’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Bleiswijk, The Netherlands.

-   -   1) Dark red flower with a large dark red-purple lip;     -   2) 1-4 peduncles;     -   3) Peduncle is medium long and sturdy;     -   4) The shape of the leaf is lanceolate and elongated to very         elongated; and     -   5) Plants are propagated by meristem tissue culture.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘CAMBLOQA’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 70-week old plants which were planted from tissue culture to a plug and then to 12 centimeter pots, and grown in a greenhouse between 20° C. to 25° C. Observations were made in September 2017. Color readings were taken under 4000-6000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2015).

COMPARISON WITH PARENTAL AND SIMILAR VARIETIES

The female parent plant of ‘CAMBLOQA’, cultivar ‘60000-0149’ (unpatented), is no longer in existence, so a meaningful comparison cannot be made.

‘CAMBLOQA’ differs from male parent ‘60000-165’ (unpatented) in that ‘CAMBLOQA’ has dark red flowers with light green tips and a dark red-purple lip with a white region toward the edge, whereas ‘60000-165’ has light red-purple flowers and a purple-red lip with light purple toward the margin.

‘CAMBLOQA’ is most similar to the commercial x Burrageara plant named ‘CAMBOPAL’ (unpatented) and a x Miltonidium plant named ‘CAMBOLYK’ (U.S. Plant Pat. No. 28,026). ‘CAMBLOQA’ differs from commercial variety ‘CAMBOPAL’ in that ‘CAMBLOQA’ has dark red flowers with light green tips and a dark red-purple lip with a white region toward the edge, whereas ‘CAMBOPAL’ has brown-purple flowers and a purple lip with white irregular spots and dark red toward the callus. Additionally, ‘CAMBLOQA’ is a taller plant with larger flowers than ‘CAMBOPAL’.

‘CAMBLOQA’ differs from commercial variety ‘CAMBOLYK’ in that ‘CAMBLOQA’ has dark red flowers with light green tips and a dark red-purple lip with a white region toward the edge, whereas ‘CAMBOLYK’ has dark red flowers and a red-purple lip with white irregular spots and darker red toward the callus. Additionally, ‘CAMBLOQA’ is a taller plant with larger flowers than ‘CAMBOLYK’. 

I claim:
 1. A new and distinct variety of x Miltonidium plant named ‘CAMBLOQA’, substantially as described and illustrated herein.
